Design of Smart Power-Saving Architecture for Network on Chip

NETWORK ON CHIP:

                        In network-on-chip (NoC), the data transferring by virtual channels can avoid the issue of data loss and deadlock. Many virtual channels on one input or output port in router are included. However, the router includes five I/O ports, and then the power issue is very important in virtual channels. In this paper, a novel architecture, namely, Smart Power-Saving (SPS), for low power consumption and low area in virtual channels of NoC is proposed. The SPS architecture can accord different environmental factors to dynamically save power and optimization area in NoC. Comparison with related works, the new proposed method reduces 37.31%, 45.79%, and 19.26% on power consumption and reduces 49.4%, 25.5% and 14.4% on area, respectively.
